We have that
x/(x+5)=(x-2)/(x+1)---------- > x*(x+1)=(x-2)*(x+5)- -----> x²+x=x²+5x-2x-10
x²+x=x²+5x-2x-10------- > 2x=10
x=5
the answer is x=5
so we have 3 folks painting 4 walls, now each one of them works for 32 minutes
person 1............. 32 mins
person 2............. 32 mins
person 3............. 32 mins
for a total of 32+32+32 = <u>96 minutes worth of work</u>. That's for 4 walls, how many minutes worth is just 1 wall?
96 ÷ 4 = 24 mins.
so to paint a wall, it takes 24 mins of work worth.
so then, to paint 7 walls, that'd be 7 * 24 = 168 minutes worth of work.
what about for 4 folks doing it? How many times does 4 go into 168? 168 ÷ 4 = 42 mins.
Answer:
The slope of the line represented by the following equation is -4
y-intercept: −1
The triangles which are possible to draw are
angles measures 30° ,60° and 90°
angles measures of 25°, 65° and 90°
The triangles must add up to 180° for it to be drawn
Answer:
3.5
Step-by-step explanation:
If the shape is half of a circle, you will be using this formula: A = π
Your radius is half of the diameter. r = d/2 = 3/2 = 1.5
Substitute r = 1.5 into the formula.
A = π
A = (3.14)
Use your calculator to find the answer and round your answer.
